The strain induced at the interface of Nd_2Fe_(14)B/Nd-rich is thought to influence on the interfacial microstructure and the coercivity. In this study, lattice constant of Nd-rich phase is evaluated in the Nd-Fe-B films with several coercivity by HRTEM. The lattice constant of fcc NdO_...
Calculate the lattice constant, a, of the cubic unit cell. If the space lattice is SC, the lattice constant is given by the formula a = [2 x r]. For example, the lattice constant of the SC-crystallized polonium is [2 x 0.167 nm], or 0.334 nm. If the space lattice is FCC, the...
In this paper we present the first investigation on the lattice structure of nanophases, α-Fe(Si) and Fe2B, in nanostructured Fe Cu Si B alloys obtained via crystallization of the parent amorphous alloy. It is found that the lattice constant of α-Fe(Si) phase is increased, whereas the...
Scanning electron microscopy images show that the inverse opal possesses face-centered-cubic symmetry with a lattice constant of 240 nm. The transmission ... P Ni,B Cheng,D Zhang - 《Applied Physics Letters》 被引量: 83发表: 2002年 Nanocrystal [Ti 14 C 13 ] to Metallocarbohedrene [Ti 8...
(BCC) lattice structure,a1=ai,a2=aj,a3=(i+j+k)a/2, with a lattice constant of ∣a1∣=∣a2∣=∣a3∣=2.8665 Å. (c) Sodium chloride (NaCl) has a face-centered cubic (FCC) lattice structure,a1=(i+j)a/2,a2=(j+k)a/2,a3=(i+k)a/2 with a lattice constant ∣a1∣=∣a2...
Fig. 3.4. Neutron density accumulation of 11 neutrons reflected coherently at boundary. Abscissa is the distance in a unit of lattice constant a from the boundary where the neutron waves reflected. When a wave is reflected, the profile is a straight line at a height 1 parallel to the absciss...
The lattice constant a of the pristine diamond was predicted to be 3.563 Å, showing good agreement with the experimental value of 3.567 Å. In particular, a supercell was built up from the equilibrium diamond cell with lattice vectors defined as [110], [\(\bar{1}10\)], and [...

Next the force constants of the metals are evaluated at this lattice constant of the alloy. The lattice dynamics and elastic constants of the Ni0.55Pd0.45 alloy are then computed by using the force constants and mass for the alloy, obtained by the concentration averages of the force constants...
Given the constant lattice distances along the 〈111〉 direction in SD, this results in a shortening of the distances between A, D and next atom along the Z-axis direction of B atom. Although no obvious hard core reconstruction is observed, this can be interpreted as a trend from the ...
